I am really learning about fuel pumps and pressures etc (I think) and wonder
if anyone can comment on the problem I have with getting a smooth running
engine at RPM below about 3600 on my 914. Could it be overmuch fuel pressure
and carb flooding with both pumps on in my parallel system? On the other hand
when doing test engine ground runs I have the pumps, filters etc in view and
there is always only one pump fully working as witness the amount of fuel
flowing through the transparent filter barrels..
Going back to some recent discussions on filters and accumulation of grot.
A good while ago I removed a huge amount of stuff from my carbs and jets,
none of which had been trapped by the filters which were as clean as a whistle.
With my briefish experience of the Rotax I find this curious.
